If n is a given number, how to get the first half of a number and second half? Ex: 9456, what I need is the first half is 94 and the second half is 56.

I can get the first half of a number using (int)(n / pow(10, (digits / 2))) this formula, but am not able to get the second half. Can anyone help here? Thank you.

I think you can use the simple process for picking up each digit using n0 and then n/=10 ,then store the first half of numbers in a variable and the other half in another.

first convert number to string , then use .length() to obtain max pow of 10 lets say = p.

then take phalf = p/2 if it is even or (p   1)/2 , if it is odd.

then do divide and modulo with pow( 10, phalf ), divide will give upper first half and modulo woill give lower second half.
